How to Find Asymptotes of Exponential and Logarithmic Functions

Subject: Mathematics

Book: Maths Mastery

Exponential functions like y=a^x typically have a horizontal asymptote on the x-axis (y=0) if a>1 or 0<a<1. Meanwhile, logarithmic functions y=log(x) have a vertical asymptote at x=0. For example, y=2^x never reaches y=0 but approaches it as x→–∞. Similarly, y=log(x) never touches x=0 but approaches from the positive side. Recognizing these boundaries is crucial for graphing or analyzing behavior at extremes (big x or near zero). This knowledge helps interpret growth or decay processes and domain constraints in advanced math or science contexts.
